System compatibility

CACR-SR20BB1AF-Y303 belongs to Yaskawa SR servo family,matched with corresponding 2.0kW USAREM servo motor. The AF hardware defines dedicated encoder interface,while suffix Y303 is factory customized firmware and modified I/O signal definition for original production machine. Widely used in chip mounters,precision X-Y positioning platforms and special automation equipment. This is a discontinued legacy servo amplifier for old production line maintenance spare replacement.

Function

CACR-SR20BB1AF-Y303 serves as high precision AC servo amplifier unit. It receives pulse position instructions from upper controller to achieve fast speed and torque adjustment. Built-in multi-level hardware protection to safeguard servo motor and drive. Y303 custom version comes with preloaded fixed parameters and optimized motion response curve to match original machine requirements.

Installation

Mount CACR-SR20BB1AF-Y303 on control cabinet panel. Wire power cable,motor cable and encoder feedback cable according to wiring drawing. Complete parameter setup and motor auto-tuning via Yaskawa servo software.

Interface

‑Power terminals for main power and motor power output

‑AF dedicated encoder feedback connector

‑Digital I/O terminal block for pulse command and alarm output

‑Front panel LED indicators for power,running and fault state

‑Onboard current loop processing and multi-point fault diagnosis circuit

Circuit feature

Compact rugged PCB layout,equipped with surge and ESD suppression circuit. Fast current loop response,stable positioning performance,good anti-interference performance for industrial cabinet environment. Custom firmware loaded for Y303 special variant.

Feature

CACR-SR20BB1AF-Y303 is obsolete Yaskawa SR series custom servo spare part. Typical failures include power board damage,encoder port breakdown,overload and overvoltage alarms. Check motor and cable integrity before replacement. Y303 customized variant cannot be directly substituted by standard CACR-SR20BB1AF without parameter validation.

Diagnostic

When overvoltage,overcurrent,overload,encoder signal loss or overheating occurs,the drive triggers corresponding alarm codes and sends fault signal to upper PLC or controller.

Built‑in function

Precision closed-loop position,speed and torque control,real-time encoder signal monitoring,multi-level hardware fault protection for servo motion system,used as customized servo amplifier spare replacement.
